Chelsea Truck Company (CTC) and KAHN® have unveiled the Series II Expedition, a remarkable and meticulously designed evolution of the INEOS Grenadier, infused with the distinctive DNA of their iconic Widebody Defender. This latest transformation transcends traditional customization, setting a new benchmark in luxury off-road motoring with a bold, adventure-driven edge.
When INEOS launched the Grenadier in 2023, it filled a void left by the New Defender, drawing a devoted following of enthusiasts who value both rugged capability and refined aesthetics. Recognizing the Grenadier’s potential, Chelsea Truck Company saw an opportunity to reimagine the vehicle, infusing it with CTC’s renowned craftsmanship and bold vision. Collaborating with KAHN®, they envisioned a vehicle that would not just meet but redefine the expectations of high-end off-road enthusiasts.
A Bold Reimagination of Design and Craftsmanship
At its core, the Series II Expedition represents the perfect synergy of Chelsea Truck Company’s design ethos and KAHN®’s visionary approach. Every detail of the Series II Expedition has been meticulously engineered to merge utility with luxury, establishing an aesthetic that commands attention both on and off the beaten path.
In developing the Series II Expedition, Chelsea Truck Company embraced an OEM+ philosophy—a concept that elevates factory standards by enhancing aesthetics, functionality, and usability without compromising on the vehicle’s inherent ruggedness. The result is a Grenadier that retains its legendary performance capabilities while embodying a newfound sophistication. With an expanded, more assertive stance and a heightened level of refinement, the Series II Expedition has become a dominant presence, exuding luxury and power with every mile.
Exterior: Striking Carbon Fibre Elements and Bespoke Enhancements
The Series II Expedition’s exterior specifications set it apart as a masterpiece of bespoke craftsmanship. Enhancements include an Exposed Carbon Fibre Dakar Central Lamp Grille featuring integrated ‘X’ masks, a 3-piece Front Bumper Valance in carbon fibre, and wide wheel arches that amplify the Grenadier’s rugged appeal. Adding to its dynamic aesthetic, 40mm wheel arches and wide wings with integrated bolt apertures make a bold statement in exposed carbon fibre.
The carbon fibre elements are meticulously balanced with military-inspired textures and finishes. The 3D military textured matte black paintwork, coupled with carbon fibre details and a matching roof, conveys a sense of stealth and durability, while the large upper roof wing and 100mm crosshair exhaust system in satin black underscore its aggressive stance.
A 30mm suspension lift paired with RS-Forged G22 light alloy wheels and robust 37-inch all-terrain tyres ensures that the Series II Expedition is as capable on challenging terrain as it is eye-catching in urban settings.
Interior: A Luxurious Nappa Leather Sanctuary
The luxury of the Series II Expedition extends into the cabin, where CTC has crafted an environment of unparalleled refinement. The front sport seats are upholstered in striking Vermillion Red Italian Nappa leather, adding a vivid contrast to the rugged exterior. Rear seats and door panels are similarly adorned in Nappa leather, featuring discreet yet distinguished CTC branding.
Every touchpoint has been considered: from the passenger grab handle to the handbrake and drive select gaitor, each component is reupholstered in premium Nappa leather, underscoring the vehicle’s commitment to luxury. The Series II Expedition’s interior creates a space that balances comfort with bold design, ensuring that occupants are enveloped in sophistication regardless of the journey.

Elevated Performance and Purpose
Beyond aesthetics, the Series II Expedition delivers an enhanced driving experience tailored to adventurers seeking both functionality and flair. Its 37-inch all-terrain tyres, coupled with a suspension lift, enable it to navigate the most challenging landscapes. Yet, despite its rugged underpinnings, the vehicle remains a refined force, designed to provide maximum comfort and control across varied environments.
This vehicle isn’t just about pushing boundaries; it’s about redefining them. The Series II Expedition sets a new standard for INEOS Grenadier conversions, offering a level of craftsmanship and exclusivity that’s rare in the off-road sector. Every aspect of the design—from the carbon fibre finishes to the lavish interior—is a testament to Chelsea Truck Company and KAHN®’s commitment to innovation and quality.
